This is beta-release v3.0 of the GtoImmuPdb. It contains the majority of features and functionality expected in the full public release. However, it remains under development and while it should not contain any critical bugs, some portions are not yet optimised and may lack full functionality or content.

GPR157 has ambiguous sequence similarities to several different GPCR families (class A, class B and the slime mould cyclic AMP receptor). Because of its distant relationship to other GPCRs, it cannot be readily classified.

2. Edgar AJ. (2007) Human GPR107 and murine Gpr108 are members of the LUSTR family of proteins found in both plants and animals, having similar topology to G-protein coupled receptors.
